I’m not usually into products, but I like this one. Remember this diy SDI DVD video out mod which lets you send high quality digital video over coax? Thanks to Pixel Magic, you can mod a variety of DVD players to add SDI thanks to the kit they’re offering. At a glance, bt.656 and bt.601 appear pretty similar, but the eval kit from the original only claims to be compatible with bt.601 while the Pixel Magic version is for bt.656.
